The sleep time is calculated as the sum of all arguments passed.
This makes the FreeBSD version of sleep functionally compatible with
the version in GNU coreutils.

The coreutils version of this command accepts a unit designation of s,
m, h, or d (for seconds, minutes, hours, days) immediately following
the number of (fractional) units to delay.
The submitted patch has been modified in one detail: the test meant to
detect the presence of the unit modified was not specific (!= 1) and
would have accepted a non-numeric initial element or extra characters
following the union. The committed version accepts only the number
immediately followed by one of the defined unit designators and no
further characters.

Support for fractional seconds has become much more widespread since
this text was originally written.

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.
This is a conservative change. It does the same thing in weird
cases like the old one. For example, 'sleep abcd' still sleeps
for zero seconds. `sleep 10.a' and `sleep 10.05aa' do the best
and not abort (ie: 10.a == 10 seconds, 10.05a == 10.05 seconds).
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
